sound problems

hi everyone, I'm quite beginner in flash,

I'm building a site which has a stop/play button inside a movieclip contained in in the main movie.... actually it works well, the problems comes when I call, from an external movie (image.swf), some external movies displayed along the main time line...by telling from "image.swf", to go to marked frames in the main movie which contained the script that calls the external movies... at one point, the music overlapes over and over again...., I can't figure out why does it happen? the movieclip "sound" is in the main movie and placed all frames long? it shouldn't be affected for the position in the mainline isn't) I've noticed that whereas the mainmovie goes ahead it works fine, but once it goes forward it starts overlaping!!!

Whyyyyyy??

Thanx in advance

If you are mixing high powered internet sound files and complex flash functions you have already gone into no-man territory and you are on your own. I have been there before and all I can tell you is to treat sound files with kid gloves!
You can call macromedia tech support but they will make you wait for hours and still will not give you an answer.

Well I guess it's not such comlicated script, probably my descritpion has maded more dificult. Probably if I use new sound =.... it won't happen but it doesn't work to me anyway.... I use this script
-------------------------------------
myMp3 = new Sound();
myMp3.loadSound("musico1.mp3", false);
myMp3.start(6);
-------------------------------------

This is placed inside a moviclip which is placed all along the main time line movie.... why it's not working? I go to sound properties (linkage) and i've made the sound exportable for actionscript, and i've upload it by itself with also the main SWF(isn't how it works?).

Help please, I do really believe it's not such difficult....

I just want a background music playing all the time.

Thanx in advance
